Examples of accidents & crash tests

Collision with oncoming traffic

Sequence of events:
While driving round a long bend to the right, a motorcyclist veered onto the wrong side of the road and collided with the front left-hand corner of an oncoming car while in an upright position. The impact of the crash threw the motorcyclist off her vehicle, causing her to bang her head against the left-hand A-column of the car and the adjoining section of the windshield.

Persons involved in the accident:
One motorcyclist and one car driver

Consequences/injuries:
The motorcyclist died at the scene of the accident due to the severe head injuries she had suffered. The car driver suffered minor injuries.

Cause/problem:
The cause of the accident was the incorrect angle the motorcyclist had adopted in order to take the corner. Due to natural inhibitions, some motorcyclists do not lean far enough into the angle required to corner safely, especially when they are inexperienced and traveling at high speeds. As it did here, this can even occur when a motorcyclist is not breaking the speed limit.

Avoidance measures, mitigation of consequences/ strategy for road safety measures:
This accident could have been prevented if the motorcyclist had adopted a less vertical angle or taken the corner at a lower speed, which would have enabled her to stay in her lane. The driver of the car had a maximum of 2.1 seconds to respond to the critical situation before the collision. He steered toward the outside edge of the road to his right and started braking, but this was not enough to prevent the accident. Inexperienced motorcyclists often do not lean into corners as far as they could. Motorcycle safety training or specialized cornering training can help many motorcyclists to find the correct balance between speed and angle and learn their own limits.
